MVVM Light is extremely popular to build client applications in XAML. It supports Windows Presentation Foundation, Silverlight, Windows 8 (RT), and Windows Phone. This toolkit consists of helper components, project and item templates, code snippets, and recommendations on building a decoupled architecture for your application. MVVM Light works great in Blend and the Visual Studio designer to enable designer-developer workflow to improve the application's user experience. MVVM Light also makes it easier to decouple the application's components and to maintain it. This course introduces each component with in-depth explanations and samples. It also shows examples inspired from real-life applications where MVVM Light is used successfully.
